Abstract
The invention relates to a joint angle measuring device, comprising a central disc, a disc face, a pointer turntable and claw hooks, wherein scales are arranged on the disc face; the central disc is provided with a miniature deep-groove ball rolling bearing, and the disc face is fixed at the front side of the central disc through a fastening piece; the pointer turntable is arranged at the front side of the disc face and penetrate through the disc face to be connected with the miniature deep-groove ball rolling bearing; the rear side of the disc face is fixedly provided with a connecting block; the claw hooks are connected with the central disc through a fastening piece; the pointer turntable is further fixedly provided with a pointer; the connecting block is further provided with a slide rod in a connection manner, and a connecting slider is sleeved on the slide rod; and the joint angle measuring device is further provided with two pairs of vanes symmetrically. When the joint angle measuring device is used, one end of the joint can be clamped by the two claw hooks which rotate along with the twist of the joint, and the twist angle and the rotation angle of the joint can be measured easily by coordination of an angle gauge, so that the range of motion of the joint can be described precisely. The joint angle measuring device is simple in structure, convenient to operate, favorable in use performance and low in cost.
Description
Technical field
The present invention relates to a kind of for medical apparatus and instruments, a kind of joint angles measuring device particularly.
Background technology
In curative activity, to measure inspection and be absolutely necessary, the error of measurement result is difficult to avoid, and the error that measurement result is brought will directly influence therapeutic effect.Therefore, in measuring process, to reduce error as far as possible.
At present, for the angular surveying in joint, current measuring methods is ocular estimate and angle block gauge measurement method.And do not have a special-purpose angular surveying instrument.Therefore ocular estimate can only be used for rough calculating or qualitative examination because the error that exists is bigger.Angle block gauge is then helpless for the windup-degree in joint.Present clinical medical development is more and more higher to the requirement of degree of accuracy, also impels every result of clinical detection digitized, precision and standardization more, describes also requiring necessary degree of accuracy for the functional status in joint.
Summary of the invention
Technical problem to be solved by this invention is at the deficiencies in the prior art, provide a kind of rational in infrastructure, measure joint windup-degree measuring device accurately.
Technical problem to be solved by this invention is to realize by following technical scheme.The present invention is a kind of joint angles measuring device, is characterized in: it comprises spider, card, pointer rotating disk and grapple; Card is provided with scale; At spider miniature zanjon ball rolling bearing is installed, card is fixed on the spider front side by securing member; The pointer rotating disk is located at the card front side and passes card and is connected with miniature zanjon ball rolling bearing; Rear side in card fixedly has contiguous block; Described grapple is 2, is symmetrical arranged, and grapple is connected with spider by securing member; Pointer is also fixedly arranged on the pointer rotating disk; On contiguous block, also be connected with litter, be socketed with the connection slide block at litter; It also is provided with 2 symmetrically arranged fins, and an end of fin links to each other with grapple respectively by securing member, the other end be connected slide block and connect.
Securing member of the present invention can use in the existing standard spare applicable to securing member of the present invention.The optimal technical scheme of securing member is: the securing member that connects fin and grapple is preferably nylon spacer, cross pan head screw and nut.Fixedly the securing member of card and spider is preferably the cross sunk screw; Fixedly the securing member of grapple and spider is preferably cross sunk screw, pad and nylon spacer.
When the present invention uses, can cross two grapples and clamp joint one end, reverse and rotate along with the joint, can measure the windup-degree in joint easily by scale of the present invention and pointer, can measure the anglec of rotation by the protractor that cooperates, thereby accurately describe the mobility in joint.Compared with prior art, joint angles measuring device of the present invention is simple in structure, easy to operate, and serviceability is good, and cost is low, is a kind of desirable joint angles measuring device.
Description of drawings
Fig. 1 is a kind of structural representation of joint angles measuring device;
Fig. 2 is the partial schematic sectional view of joint angles measuring device;
Fig. 3 is the structural representation of grapple and litter.
The specific embodiment
Following with reference to accompanying drawing, further describe concrete technical scheme of the present invention, so that those skilled in the art understands the present invention further, and do not constitute the restriction to its right.
Embodiment 1, and with reference to Fig. 1～3, a kind of joint angles measuring device: it comprises spider 8, card 1, pointer rotating disk 2 and grapple 4; Card 1 is provided with scale; At spider 8 miniature zanjon ball rolling bearing 9 is installed, card 1 is fixed on spider 8 front sides by securing member; Pointer rotating disk 2 is located at card 1 front side and passes card 1 and is connected with miniature zanjon ball rolling bearing 9; Rear side in card 1 fixedly has contiguous block 10; Described grapple 4 is 2, is symmetrical arranged, and grapple 4 is connected with spider 8 by securing member; Pointer 3 is also fixedly arranged on pointer rotating disk 2; On contiguous block 10, also be connected with litter 7, be socketed with connection slide block 6 at litter 7; It also is provided with 2 symmetrically arranged fins 5, and an end of fin 5 links to each other with grapple 4 respectively by securing member, the other end be connected slide block 6 and connect.
During enforcement, clamp an end in joint with grapple 4, keep pointed center line 0 graduation mark, making the joint angles measuring device follow the joint reverses and rotates, keep grapple 4 and joint to reverse synchronously during torsion knuckle, be used to indicate the pointer 3 of angle along with the rotation of joint angles measuring device, pointer 3 is being with pointer rotating disk 2 to rotate, read the joint windup-degree in card 1, thereby realize the measurement of windup-degree.The use of use level hornwork can easily obtain windup-degree and the anglec of rotation in joint, for doctor's treatment provides range of motion foundation accurately.
